Modern networks are becoming more complex. New technologies -- such as artificial intelligence, the internet of things, multi-cloud environments, network virtualization and software-defined networking -- can add great complexity to the overall network infrastructure.
As a result, network monitoring and visibility are also becoming more complex. End-to-end and real-time monitoring are especially difficult.
Clearly, effective network monitoring can offer a great deal of benefits for network managers. Namely, monitoring and visibility can help troubleshoot network problems, validate performance-based configurations and improve network security measures.
While multi-cloud environments have gathered more interest recently, the task to monitor these complex environments becomes more challenging for network managers. Although cloud-based systems might promise greater flexibility, these environments can also complicate matters as network managers might relinquish some network control and visibility. According to industry surveys, network managers routinely cite public cloud monitoring and management as one of their top problem areas. And as the cloud handles an increasing amount of network traffic, network managers need to monitor paths in and out of the cloud.
Multi-cloud architectures might require rethinking some architectural components. By dissecting network components, organizations can start to envision the requirements of their multi-cloud management strategy. Network managers will need an in-depth knowledge of their networks, including network traffic paths, event correlation and top network exceptions.
In this guide, networking experts explore the challenges of network monitoring when it comes to multi-environment deployments, and they offer tips on how to tackle these new, complex worlds.
